YOOOO I NEED HELP on this too and do these
Rus_ich [418]

Answer:

8. 504ft²

9. 4970yd² (rounded to 3 s.f.)  

Formulas (For easy reference):

Area of rectangle = length × breadth

Area of circle = pi×r×r

Circumference of circle = pi×r×2

-----------------------------------------------------------------------------------------------------------

Step-by-step explanation:

8. You know a box has 6 sides, and there are 3 types of surfaces that are different from each other, and you have to multiply each side by 2 cus there are the front and backside (You can draw the box with its dimensions to see the 3 types of surfaces and why I multiplied by 2):

(2×12×6) + (2×12×10) + (2×6×10) = 144 + 240 + 120

                                                   = 504ft²

9. The net of a cylinder contains two circles of radius 24yd and one long sheet to wrap around the circles with the length that is the circumference of the circle (so that it can wrap around the two circles) and a width which is the height of the cylinder (9yd).

2 Circles = 2×pi×24×24

                = 1152pi

Long sheet = 9×24×2×pi

                   = 432pi

Now we can add all of them together:

432pi+1152pi = 1584pi

                      = 4970yd² (rounded to 3 s.f.)

Answer:

OPS and QPN

Step-by-step explanation:

Vertical Angles are the angles opposite each other when two lines cross

"Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down.
